This adds build caching and build scans.
The changes required disabling scans when using the maven invoker
plugin in order to not cause duplicate build scans when invoking other
maven builds. There is also an empty `.mvn` folder in the
spring-boot-starters project to prevent duplicate build scans as well
since there is no way to pass properties to the maven-javadoc-plugin.
The checkstyle plugin was causing a cache miss with the
`propertyExpansion` because it contains an absolute path. The absolute
path is now ignored and instead the files are added as inputs to the
checkstyle plugin. This only enables the local build cache. The remote
cache is not yet enabled.
On my local machine:
./mvnw clean install build times go from about 30 minutes to about 10 minutes.
./mvnw clean install -Pfull build times go from about 60 minutes to about 13 minutes.

Previously, Maven's default behaviour was relied up which resulted
in the artifact ID being appended to each URL as it was inherited.
This behaviour can only be disabled in Maven 3.6 and later, a version
that we cannot use due to an incompatibility with the Flatten Plugin.
This commit works around Maven's default behaviour by defining
properties for the SCM URL, connection, and developer connection and
then explicitly defining the settings in each pom using these
properties. The explicit definition of the properties in each pom
prevents them being inherited from the parent, thereby disabling the
unwanted appending of the artifact ID to the URL.
Fixes gh-18328
This commit restores the read-only `finalName` so that its value can
be lazily resolved against `${project.build.finalName}`.
While doing the evaluation ourselves and not relying on a dedicated
field at all would have been better, the evaluation increased the
number of required dependencies for no good reason.
IDEs should not offer auto-completion for that read-only field and it
is not published in the generated site either.
Closes gh-16456
A read-only plugin parameter can still be set by the user which leads
to an invalid repackaged archive. This commit actually ignores the field
and uses the standard attribute instead.
Closes gh-16202
This commit updates the documentation to reference the default execution
id of the `repackage` goal when a project uses
`spring-boot-starter-parent`.
Closes gh-14835
